Momentum Calculator
Momentum is mass times velocity and is conserved in every collision, which is what makes it so useful for working out what happens afterwards. The combined velocity here assumes a perfectly inelastic collision, where the two objects stick together.

Total momentum
Velocity if they stick together
Total kinetic energy
Energy lost in a stuck collision
